Kim Kardashian wants to be single.

The socialite - who split from New Orleans Saints football player Reggie Bush last month - is ready to play the dating game and admits it will be strange for her to not be in a relationship.

She said: "I think I'm such a relationship kind of girl for years, I think it would be really refreshing and I'm having a good time being single. I can't even remember the last time I was single. I work so much that to be honest, I'm not really even thinking of dating."

Although she is ready to be romanced, Kim has refused to confirm whether or not she kissed soccer superstar Cristiano Ronaldo during a recent trip to Miami.

She added in an interview on the Kyle and Jackie O breakfast show on Sydney's 2DayFM station: "According to the US, I'm kissing a lot of people! Every time you are in the same place as someone, they always say you're dating them so at this point I've given up. Who is the source? I'd love to know, I want to work for a blog and find out who these sources are."

Kim also revealed she wants to set up her sister Kendall with teen pop sensation Justin Bieber.

The 29-year-old star said: "I actually put up on my website that I think he should date my sister Kendall. I think Justin Bieber is adorable, he's definitely way too young for me but I'd still love to hook him up with my sister."
